Sinx=\frac{opposite}{hypotenuse} =\frac{ \sqrt{2} }{2}
     opposite=\sqrt{2}
     hypotenuse=2

Adjacent^{2}+(\sqrt{2 })^{2 }= 2 ^{2}
<span>Adjacent^{2}+2=4
</span><span>Adjacent^{2}=2 
</span>Adjacent=\sqrt{2}

cosx=\frac{ajc}{hyp}= \frac{ \sqrt{2} }{2}
Tanx=\frac{opp}{adj} =  \frac{ \sqrt{2} }{ \sqrt{2} }

The hypotenuse of a right triangle is four times the length of one of the legs. The length of the other leg is 1500⎯⎯⎯⎯⎯⎯⎯⎯√ fee
Mrac [35]

Answer:

Step-by-step explanation:

So this is just playing with the pythagorean theorem

a^2 + b^2 = c^2 with a and b as legs and c as the hypotenuse.

Let's say a is equal to 1500 so then c is 4 times b

1500^2 + b^2 = (4b)^2  Now we just treat this like a normal algebraic expression

2,250,000 = 16b^2 - b^2

2,250,000 = 15b^2

150,000 = b^2

sqrt(150,000) = b

100sqrt(15) = b

You can check this now.

1500^2 + sqrt(150,000)^2 = c^2

sqrt(2,250,000 + 150,000) = c

sqrt(2,400,000) = c

400sqrt(15) = c Which fits the requirement of c = 4b

Debra found that 6 of the 24 students in her class own a cell phone . What is the ratio of students that own a cell phone to stu
ale4655 [162]
6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not. 
24-6=18. Thus, the ratio would be 6:18
